use the S2 TRM for the S2-Mini instead the C3-TRM which was linked in the post

Flashing ESP32

Hi everyone,

I want to intergrate the ESP32-S2-MINI module into my design. Can I use the JTAG interface for debugging and flashing as well? If JTAG serves both features do I need to include USB connector and USB to UART Bridge?

Thanks

ESP32-S2-MINI-1 - External Interrupts

Hi everyone, I want to intergrate the ESP32-S2-MINI-1 module to my design. My design requires 18 external interrupts and looking the datasheet of the ESP32-S2-MINI-1 module I see that there are available 25 gpios. However what it is not mentioned is what gpios can be used as external interrrupts... ...

When I upload the same sketch ...

Re: esp32 does not read correct analogue values

I started receive some measurements but are quite inaccurate. I compared the voltage readings of esp32 with that of my multi meter and there is high deviation. For example with the multimeter I read 0.14V while with esp32 0.01V. I suppose that this is not some issue of my code. The ADC reading is qu...

Control 5V relay with ESP32 DEVKITC

Dear all,

I've got an ESP32 Devkitc and I need to control a 5V relay through a GPIO pin.

I will supply 5V (using a battery and dc/dc converter) into the 5v pin of ESP32. The GPIO outputs is going to be 5V OR 3.3V?

In general is it possible to control a 5V relay with ESP32?

Thanks is advance
